Right Angle! (:
Right angles are formed by perpendicular lines. If the lines would extend, to make two intersecting lines, they would form four right angles. Perpendicular lines are written like this: . From its shape, you can already tell that it forms at least two right angles.
A perpendicular line is formed when two lines meet at a right angle. Opposite angles in a perpendicular line are parallel to each other.
If they share a ray, then they are basically combined together and since complementary angles add up to 90 degree angles a right angle is formed.
A triangular prism has two right angles. Each end of the prism, which is a triangle, has one right angle. The third right angle is formed where the two rectangular sides meet. So, in total, a triangular prism has two right angles.
180 degreesAlso known as a straight angle.
A right angle.
An angle is formed by the intersection of two straight lines. If the lines are perpendicular, they will form right angles.
Right angles aren't formed by other angles - it is already an angle itself. However, if you bisect a right angle, it becomes two acute angles.
Right angles - or 90 degree angles.

If you mean the capital letter "F" there is 3.
The answer to that is a bisector. The two angles formed by this has the same angle.
A perpendicular line is formed when two lines meet at a right angle. Opposite angles in a perpendicular line are parallel to each other.
A right-triangle has a right angle (90o) and two acute angles.
Not necessarily. The two equal angles in an isosceles triangle must both be acute angles. If they were right angles or obtuse angles then a triangle could not be formed. If the two equal angles are less than 45° each then the third angle is an obtuse angle. If they are both 45° then the third angle is a right angle and if they are both greater than 45° then the third angle is an acute angle.
